I have done everything possible to get my kids involved in hunting. Every time out whether it be scouting, camping or during the actual hunt, I will challenge them to find their way back without using any electronics (GPS). Also without a compass. They know by now that I am going to challenge one of them, so right off the bat when leaving our vehicle or camp they will start picking out land marks to help them out. Makes me and them feel confident that if we were to somehow separate that they will be ok.
Have them also start your evening camp fires with flint. They learn real quick what will work as a starter. With the pressure of all the electronics today their entertainment could easily be staying at home all weekend and summer. If they are into video games, buy them one of the hunting games and have a contest with them on whose trophy room will be the most impressive. Also a couple of other things, make sure they always carry a whistle and plenty of matches/lighters along with their flint. Check their backpacks occasionally to make sure they are prepared. If they are without toilet paper one time they will learn real quick to start doing a better job. This has worked for me! Remember they are our future to conservation and our hunting heritage. My best memories hunting have nothing to do with harvesting an animal, but they are instead the conversations and jokes I have with my kids. Good luck!
